18.104.22.168.8 The Reference Lines Tab
For 2D graphs in Cartesian coordinates, you are allowed to add multiple vertical/horizontal reference lines and fill the area between paired reference lines.
Reference Lines at Value
To locate the reference lines, you can enter space-separated position values in this text box or select a reference column(by clicking the Select Column interactive button beside this text box) from worksheet.
- Fill the area between every odd number reference line and its next even number reference line, such as RLine 1 ~ RLine 2, RLine 3 ~ RLine 4.
Alternate Fill Include Axis Begin and Axis End
- Do Alternate Fill including Axis Begin and Axis End. The filling order is Axis Begin to RLine 1. Axis End will be the last fill to if the custom line number is even.
You can refer to this tutorial to learn how this option works.
Display Box for Reference Lines
List all reference lines. The reference lines Axis Begin and Axis End will listed at top of this table by default.
At Axis Value
Show the position of added reference lines.
Specify whether to show the reference line at current axis value.
Select a reference line from the drop-down list which current reference line should be filled to. If you've selected any Alternate Fill check box above, this column will show the pairing lines and be not editable.
Specify whether to show label for the reference line.
Specify what to be shown as label for each reference line. The default setting is <value as entered>, which means showing the position value as label for the current reference line. And you can also enter custom text in this column by double-clicking on the cell to enable the in-place edit mode.
Specify the position of the labels. For Vertical lines, possible positions are top/middle/bottom of the reference lines; For Horizontal lines, possible positions are left/middle/right of the reference lines.
There are three buttons under the display box:
|| Insert a new reference line before the one you selected in display box.
|| Delete one or more reference lines that are selected in the display box. (i.e. the reference lines other than the Axis Begin and Axis End ones). To select multiple lines, hold down Ctrl key and click on the reference line entries one by one.
|| Open the Reference Lines dialog for further style customization of the reference lines.
|Note: To enable Insert and Delete buttons, you should clear Reference Lines at Value at first.
Details dialog for Reference Lines
This dialog can be opened by clicking the Details... button in the Reference Lines tab of Axis dialog. It is used to customize formats and styles of all reference lines.
At Axis Value
Show the position of current reference line and it is not editable. It only appears for custom reference lines(excluding Axis Begin and Axis End).
The Show check box is consistent with the Line check box in the Display table. You can use it to show or hide the reference line.
Unchecking Auto Format check box to customize the Color, Style and Thickness of current reference line.
Customize Fill Pattern between paired reference lines.
